FIELD: industry of building materials. SUBSTANCE: invention relates to methods for preparing cellular concrete mixture that can be used in making articles made of cellular concrete based on cement binding agent. Method for preparing cellular concrete mixture involving preparing solute component with addition of gas-forming agent to it and the following stirring the solute component is stirred for 1-2 min with technical foam beaten up in high-speed mixer at 600-800 min-1, water temperature 20-25 C and addition to the prepared mixture a gas-forming agent and repeated stirring up to uniform state for 1-2 min. Invention provides reduction of an average density and heat conductivity of articles. EFFECT: improved preparing method and enhanced valuable properties of articles. 2 tbl, 1 ex
